• How to Lease the Internet in Your Spare Time 

      Feamster, Nick; Gao, Lixin; Rexford, Jennifer (Georgia Institute of Technology, 2006)
      Today's Internet Service Providers (ISPs) serve two roles: managing their network infrastructure and providing (arguably limited) services to end users. We argue that coupling these roles impedes the deployment of new ...
    • Network-Wide Prediction of BGP Routes 

      Feamster, Nick; Rexford, Jennifer (Georgia Institute of Technology, 2006)
      This paper presents provably correct algorithms for computing the outcome of the BGP route-selection process for each router in a network, without simulating the complex details of BGP message passing. The algorithms ...
    • SDX: A Software Defined Internet Exchange 

      Gupta, Arpit; Shahbaz, Muhammad; Vanbever, Laurent; Kim, Hyojoon; Clark, Russ; Feamster, Nick; Rexford, Jennifer; Shenker, Scott (Georgia Institute of Technology, 2013)
      Deploying software-defined networking (SDN) at Internet Exchange Points (IXPs) offers new hope for solving long-standing problems in interdomain routing. SDN allows direct expression of more flexible policies, and IXPs ...
    • Simpler Network Configuration with State-Based Network Policies 

      Kim, Hyojoon; Gupta, Arpit; Shahbaz, Muhammad; Reich, Joshua; Feamster, Nick; Clark, Russ (Georgia Institute of Technology, 2013)
      Operators make hundreds of changes to a network’s router and switch configurations every day—a painstaking, error-prone process. If the network configuration could instead encode different forwarding behavior for different ...
